Three companies in the top 50 are close to Seattle, including:
#5 Microsoft (2,829 patents)
#40 Boeing (901 patents)
#50 Amazon (750 patents)
You can search the USPTO Patent Full-Text and Image Database to find patents from other companies. For instance, in "advanced search," AN/Starbucks retrieves patents assigned to Starbucks. Take a look at, say, Patent 20110088560, "Machine for Brewing a Beverage Such as Coffee and Related Method."

To find patents from other local innovators. I used "advanced search" again:
(AS/WA AND ISD/2014): 5456 patents.
AS/WA means that the patent assignee is in Washington, and ISD/2014 means that the issue date was 2014.
The first hit—"Apple tree named 'Regal 13-82" (plant patent 25,189)—reminds us that agriculture is an important part of our economy. Apple production was worth $2.25 billion in 2012.

The patent database is fun to play around with, whether you're interested in patent law or just curious about inventions.
